Chapter 1 - MIB Structure MIB Reference Manual
VP500 Communication Unit 2
All parameters in the MIBs have been configured by default upon start
up. However, if you need to modify some of these parameters (for
example, parameters related to the country in which you are), use a
SNMP browser.
Storage
Clauses In addition to the standard MIBs clauses, there are two STORAGE
clauses for storage purpose:
Persistent
Volatile
Persistent Parameters
Persistent parameters are saved into the VP500 communication unit’s
memory and restored when the unit is rebooted or restarted. The only
way to change the value of a persistent parameter is to manually
update it with a SNMP browser or by provisioning a new configuration
file.
Volatile Parameters
Volatile parameters are lost every time the VP500 communication unit
is rebooted. This type of parameter includes toggling parameters such
as requesting a configuration file or a software download.
Statistics are
also volatile parameters that are lost every time the unit is rebooted.
Changing a
Parameter
Value Changing a parameter involves contacting the VP500 communication
unit with any SNMP MIB browser. You can use the built-in SNMP editor
of the Unit Manager. See the
IP Communication Server Administration
Manual for more details. Be sure that you use the MIB files that match
the version of the MIB located inside the current software build of the
unit.
You must then locate the proper parameter to modify and change its
value. Most of the parameters will require that you reboot the VP500
communication unit. A reboot may be software-initiated or manually
initiated with the power switch. It will delete all statistics stored and will
overwrite all volatile parameter values in the configuration file. A reboot
will also reinitiate the entire unit’s initial provisioning sequence.
Switching
Protocols The MIB structure contains three MIB files, but only two are actually
used at the same time:
Note: The AT-VP504E FXO communication units can only run the SIP
signaling protocol.
